Title: Digital computer organization
IPC: G06F12/06
Filed: 1973-06-14
Abstract: 1416959 Data processors GOODYEAR AEROSPACE CORP 14 June 1973 [12 July 1972] 28356/73 Heading G4A A digital computer includes an associative processor control memory having a number of separate memory units. Intermediate data and commands from the computer or elsewhere may be stored and accessed. Control programs are stored in the units. Segments of the programs are transferred between the units by a pager. A logic network (port logic) allows access to the units on a preset priority basis. A processor control network controls the manipulation of data in associative arrays in response to the programs. There are several such arrays operable in parallel, and each can access and operate on data in the array in bit-oriented and wordoriented mode. The embodiment described, Fig. 1, has three memory units forming the control memory 18. One unit is formed as a core store for the control programs. The other two units are solid state. One is a high-speed buffer. The other is organized as three pages, one of which contains frequently-used micro-programs. One of the other two pages provides instructions while the other is being loaded by pager 24 from the core store, and vice versa. Under control of port logic 26 a memory unit can be connected to allow control unit 16 to read an instruction from it, to control unit 20 for reading an instruction, or to the pager to load a new page. The processor control network 16 (and Fig. 3, not shown) receives from memory 18 commands to be executed immediately. It includes counters designating the field relevant to the operation indicated by the command and also designating the number of cycles pertinent to a loop command. Network 16 selects the required associative array 12, determines its mode of operation, and controls the apllication of masks and the shifting of data within the array. Each array includes a solid state 2<SP>n</SP> Î 2<SP>n</SP> bit matrix and an associated unit which operates in bitoriented or word-oriented mode to perform parallel logic or arithmetic on data in the array. Each mode uses the same read-write lines and the same arithmetic/logic unit. A permutation network in the array arranges the order of data to or from the matrix. Application to radar is mentioned.

Class 38 (v) A slow-break switch, suitable for alternating currents, comprises a movable contact strip 17 operated by a dolly 16 against the action of springs 18 which support the strip, the strip being free to "float" but anchored to a fixed part of the switch by a loose or slidable pin 21. As applied to the switch of Specification 667,462, the springs 18 are housed in recesses 19 in a housing 20 having a central aperture 23 for the pin 21 which is a loose fit therein, the lower end of the pin being turned over at 24 and the other end being rivetted over the contact at 22, so as to form a sub-assembly, comprising the housing, pin, springs and strip 17, which may be fixed to the switch base. The pin may be replaced by a screw Fig. 8 (not shown). A bowed spring 26 is placed between the strip 17 and the dolly so as to take up slack in the latter. In a modification, Fig. 9, this spring 26 is replaced by a member having upper and lower limbs 28, 29, embracing the contact and urged upwards into contact with the dolly by a spring 31 which surrounds the pin and may bear on an abutment 32 on the housing, or on a collar on the lower end of the pin. Alternatively, instead of mounting the spring 31 around the pin, it may be arranged in a separate recess in the housing 20. In a further modification, Fig. 11, the springs 18 each surround a pin 21 and are arranged on the dolly side of the strip 17, the springs being compressed between the base 10 and the heads of the pins. In a further arrangement, Fig. 13, the heads of the pins are formed by the turnedover ends 37 of a U-shaped member 39 extending between the dolly and strip 17, a bowed spring 26 being arranged between member 39 and the dolly.

Title: Improvements in and relating to electrical systems
IPC: H01Q19/13
Filed: 1958-09-05
Abstract: 860,521. Aerials. PHILCO CORPORATION. Sept. 5, 1958 [Sept. 5, 1957], No. 28567/58. Class 40 (7). A wide-band directive antenna system having a high gain comprises a paraboloidal reflector 10 at the focus of which is arranged a primary element consisting of a flat element and a cone. The axis of the primary element is the same as the axis of the reflector. The element may be supported by a tube 18 extending from the centre of the reflector and containing the coaxial feeder 22. The cone 24 is mounted on the end of tube 18 by set-screws 42 so that its apex end is furthest from the reflector. It is formed as a solid unit of conductive material with an axial bore 30 through which the feeder is led. At the apex of the cone the outer conductor of the feeder is flared out and soldered to the cone surface; the inner conductor continues for a distance S and is soldered to an axial opening in disc 26. The disc may be supported from the cone by means of a cylinder 28 of insulating material or by means of spaced insulating pillars. The apex angle of the cone and its slant height are chosen to give a radiation pattern in which the major part of any energy radiated is directed into the reflector. A beam is thus formed substantially as shown and, as almost no energy falls on the centre of the reflector, the primary element does not obstruct the radiated beam nor is mismatch caused by energy directed at the reflector returning to it. The electric vector of energy radiated by the primary element is parallel to the axis. To provide a fan-shaped beam instead of the substantially conical beam of the abovedescribed arrangement the disc may be replaced by an elongated plate, which can be regarded as the disc with equal upper and lower sectors removed, or, in the limit, by a rod of a length corresponding to the disc diameter.

Title: Improvements in or relating to engine starting apparatus
IPC: F02N15/06
Filed: 1927-10-29
Abstract: 279,895. Delco-Remy Corporation, (Assignees of Chryst, W. A., and Elsy, G. W.). Oct. 30, 1926, [Convention date]. Turning gear.-In an electric starter having a pinion 30 mounted on a motor-driven shaft 22 for longitudinal and rotary movement and automatically de-meshed from the engine gear 31 when the engine starts, a manually operable device for shifting the pinion axially into mesh with the engine gear, and for rotating the pinion if its teeth clash with those of the engine gear, comprises two members 51, 52 normally movable in unison along the shaft but one capable of limited angular movement relatively to the other and around the pinion shaft. As shown, the pinion 30 is mounted on helical splines 23 on the shaft 22. The member 52 is a sleeve supported on a hub 60 and having teeth 54 for engagement with the bevelled ends of the teeth of the pinion and a helical slot 53 engaged by a. pin 51 on a lever 42 actuated by a pedal 47. The slot 53 is of variable pitch, so that on depressing the pedal the tendency of the pin 51 to move the sleeve 52 longitudinally is at first greater than the tendency to rotate the sleeve. The tendency of the sleeve to rotate is also checked by a floating disc 81 of yieldable material, interposed between brake discs 80, 82 on the shaft 22 and the sleeve, the discs being normally held in engagement by the spring 50 on the pedal 47. If the teeth of the pinion clash with those of the gear 31, the sleeve and pinion are rotated by means of the pin and slot until the teeth are in register. When the pinion is nearly fully in mesh, the lever 42 engages the switch plunger 43 of the starting motor, and the pinion 30 moves away from the sleeve 52 into full mesh with the gear 31 and drives the gear. An end stop for the pinion consists of a spring ring 25 applied to engage a recess 33 in the pinion and to prevent axial movement of the pinion due to variations of the torque required to turn the engine. When the engine starts, the pinion 30 and sleeve 52 are moved automatically away from the gear 31, the movement being allowed by the slot 53 even if the pedal 47 is still depressed. The splined part of the shaft 22 is reduced between lines 23a, 23<b> in order to prevent drifting of the pinion into mesh with the engine gear while the engine is running. In the event of backfire during the meshing operation, the pinion will be moved to the right in Fig. 1, out of engagement with the sleeve 52.

No. 28953/56. Addition to 768,325. Class 100(1). [Also in Group XXIV] Apparatus as claimed in the parent Specification comprises a one-way clutch and eccentric means in the transmission to the means for advancing the material to be cut and stacked, which clutch and eceentric means serve in operation to provide an intermittent advance of the material. Feeding webs. The material 1 to be cut and stacked is fed on continuously driven rollers 2, 3, 4 (Fig. 1) and jockey rollers 5 and 6 movable in a vertical plane to take up variations in length due to the subsequent intermittent feed of the web. After passing over a roller 7 the web is fed by rollers 8, 9 and 10 to the cutting apparatus. The roller 8 is mounted on shaft 11 to which is fast a gear 12 meshing with a gear 13 on a shaft 14. A continuously rotating drive shaft 23 is provided with a gear 24 which drives a gear 25 fast on a shaft 26 on which is mounted an eccentric device 16 (see Group XXIV) having an eccentric pin 29 (Fig. 3). The pin 29 is connected to one end of a chain 15a the other end of which is connected to a spring 15b and the intermediate portion of which passes over a chain-wheel 15c connected by a shaft to a one-way clutch 15 also connected to the shaft 14. The arrangement is such that as the pin 29 moves through the path A B C the shaft 14 rotates whereas as the pin 29 moves through the path C D A the shaft 14 remains stationary. The amount of rotation of the shaft 14 and therefore the length of web 1 severed depends upon the eccentricity of the pin 29. The feed rollers 8, 9 and 10 are reciprocated axially so that alternate cut lengths of web are displaced to the right and left respectively. To this end a cam 44 is provided on an eccentric disc 17 fixed on the continuously rotating drive shaft 23. The cam 44 has a raised portion a and a depressed portion c cooperating with a cam follower 43 connected to the shaft 11 of the roller 8. Thus as the cam follower 43 rides on to the portion a of the cam 44 the rollers 8, 9, 10 are moved to the right and as the follower 43 rides on to the portion c the rollers are moved to the left by means of a spring 45. Sheet cutting and delivery apparatus. The web 1 is cut and stacked by means of a fixed blade 21 and a reciprocating blade 19 to which is attached a pusher element 20 for reciprocation with the blade 19. The pile is formed between a table 22 and the undersurface of the fixed blade 21. The movable blade 19 is reciprocated through a linkage culminating in a cam follower which rides on the periphery of the eccentric disc 17 which latter is provided with raised portions 18.
